The web store 'Open In Excel' button does not work for Mac users. Excel indicates that it is downloading some file but then nothing happens. I'm sure expected behavior is that the workbook opens and installs the add-in to Excel. Here is a video showing this, on Excel v16.40:

I became aware of this issue because some of our customers have contacted us, asking why the add-in wasn't working. Who knows how many potential customers we have lost because they simply thought the add-in wasn't supported on their system and moved on. Very frustrating, please fix this.
